Wera 851/4 PH/S #2 PlusMinus Screwdriver Bit, 1/4" Hex x 70mm (05059721001)

Stop stripping terminal block screws and circuit breaker connections. The Wera 851/4 PH/S #2 PlusMinus Screwdriver Bit (05059721001) is specifically engineered for electrical and HVAC installations where combination Phillips/Slotted screws are standard. Standard Phillips or flathead drivers often slip or cam out, but Wera's precise PlusMinus geometry interlocks with combination profiles to deliver maximum torque transfer without damaging fastener heads.

Crafted from Wera's tough-viscous tool steel, this 70mm extended bit absorbs peak torque loads during power driving, drastically reducing tip wear and breakage on demanding jobsites.

Key Features

• Specialized PlusMinus Profile: Designed for exact fitment on combination Phillips/Slotted screws found on electrical terminal blocks, switchgear, relays, and fuse boxes.

• Tough-Viscous Steel: Hardened German-engineered tool steel prevents premature tip damage and chipping under heavy torque loads.

• 1/4" Hex Drive (70mm Length): Fits all standard 1/4" quick-release bit holders and power drivers with extra length to reach deep-set terminals.

• Wera Series 4 Shank: Standardized according to DIN ISO 1173-F 6.3 for broad power tool compatibility.
